ABSTRACT:
An electrical connector and method for providing an electrical connection wherein a receptacle having a current-carrying cable is insertible into a plug having a current-carrying cable and the cables are interconnected providing electrical connection therebetween. An endless spring coil of circular form having closely spaced turns each at an angle to its tangent to the circular form, when uncompressed, is inserted into an annular groove on the plug prior to insertion of the receptacle. When the receptacle is inserted into the plug, the coil is radially compressed thereby reducing the spacing between the turns and increasing their slant and wiping the coil along the contacting surfaces of the plug and receptacle to present the electrical effect of a solid coil and to minimize radio frequency and electromagnetic interferences.
